What words trigger "expanded broad match" in google keyword suggestion sandbox?

[tphyahoo]

Hi, I am playing with

https://adwords.google.com/select/KeywordSandbox

the google keyword suggestion sandbox. Basically this suggests three categories of "related words."

1) More specific words
2) Additional Keywords to Consider
3) Expanded Broad Match

I usually get lots of suggestions for 1 and 2, but I have tried many keywords, and have not yet managed to trigger suggestions for category 3.

I'm not sure if this matters but I'm not logged into adwords, just using the generic form. Do you need to be logged into a campaign to trigger expanded Broad Match? I don't see what you would but... ??? Or has this feature not been implemented yet?

Can anyone give me an example of a word to put into the sandbox that triggers expanded broad match?

Thanks!

Thomas.
